Probability vs. Proof in Genealogical Conclusions

Date: April 8, 2026 

Time: 7:00 p.m. – 8:15 p.m. 

Location: Zoom

Recording: Yes 

Genealogists often speak of “proving” relationships and identities—but what does proof really mean in a field built on incomplete, conflicting, and sometimes ambiguous evidence? 

This Genealogy Café session will explore the distinction between proof and probability in genealogical reasoning. Through guided discussion and case-based exploration, we will examine how conclusions are formed, how evidence is weighed, and how confident we can—or should—be in our findings. 

Rather than a formal presentation, this session will use a low-preparation, discussion-driven format with minimal visuals, encouraging participants to engage directly with the concepts and with each other. Attendees will be asked to consider real-world scenarios, evaluate competing interpretations, and reflect on how they communicate confidence in their own work. 

Topics will include: 

– What “proof” means in genealogy — and what it does not

– How the Genealogical Proof Standard supports reasoned conclusions rather than certainty

– Evaluating competing hypothesis and resolving conflicting evidence

– Using confidence language in written conclusions

This format reflects an ongoing effort to make Genealogy Café a space for professional-level dialogue and shared problem-solving, rather than lecture-based instruction. 

Although Genealogy Café is typically a CAPG member benefit, this session is open to a wider audience. Guests and colleagues are welcome. 

📌 Reminder: The March Genealogy Café session recording remains available for those who would like to view or revisit it.
